SPRING- HINGE.

SPECIFICATION forming part of Letters Patent No. 636,322, dated November '7, 1899. Application filed June 10,1899. Serial No. 720,057. (No model.)

To all whom, it may concern:

Be it known that LALBIN DANIELsoN,-a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Spring-Hinges, of which the following is a specification.

This invention relates to that class of doorhinges known as double-acting springhinges operating to automatically close the door by causing it to swing into normal posi tion when opened in either direction; and it consists in certain peculiarities of the construction, novel arrangement, and operation of the various parts thereof, as will be hereinafter more fully set forth, and specifically claimed.

The object of my invention is to provide a spring-hinge of the above-named character which shall be simple and inexpensive in construction, the tension of which may be regu- In order to enable others skilled in the art to which my invention pertains to make and use the same, I will now proceed to describe it, referring to the accompanying drawings, in which- Figure 1 is a central vertical sectional view through the hinge and a portion of the door, door-casing, and floor. Fig. 2 is a plan sectional view taken on line 2 2 of Fig. 1. Fig. 3 is a similar View taken on line 3 3 of Fig. 1. Fig. 4 is a like View taken on line 4 4 of Fig. 1. Fig. 5 is a perspective view of the ten-, sion-regulating collar. Fig. 6 is a similar view of a collar or sleeve located on the upper port-ion of the spindle. Fig. 7 is a perspective view of the collar or sleeve located on the lower portion of the spindle. Fig. 8 is a perspective view of a portion of the'spindle; and Fig. 9 is a vertical sectional view of a portion of the tension-regulatin g collar and the upper sleeve or collar, showing the means of securing the two together.

Similar letters refer to like parts throughout the different views of the drawings.

A represents the casing of my hinge, which is preferably cylindrical in shape and let into the floor A, as shown in Fig. l of the drawings. The lower portion of the casing A is provided with a cup at, in which are located a number of antifriction-balls a, on which the lower end of the spindle B will rest. The upper portion of the casing is-provided with a horizontal extension a through which is passed screws 1), used to secure it to the floor, as well as to secure the cover C in place, which cover is of a shape to correspond with the form of the casing and is provided with a slot 0 to permit of access to the tension-regulating collar D, which is provided with a series of openings 01 to receive a rod used for turning said collar when it is desired to regulate the tension of the spring. The spindle B has its upper end formed with a rectangular portion 1) to fit into a suitable socket in the plate E, which is secured to the lower portion of the door E, which door is provided at its upper portion with a suitable pivot, (not shown,) so as to allow it to swing back and forth. The plate or socket-piece Eis inserted in a suitable mortise e in the lower portion of the door and may be more firmly secured in position by means of plates E located on the sides of the door and-secured thereto as well as to the piece E by means of screws cf. The upper and lower portions of the spindle B are preferably enlarged, as shown in Fig. 1, and has diametrically-projecting lugs b and b to engage the collars F and G, respectively. The collar F is provided with an upwardly extending lug f, against which the lug b on the spindle will contact, and with a downwardly-projecting lugf to contact with the lug a on the lower portion of the casing. The collar F is also provided with a recess f to receive the lower end of the spring H, which is coiled as shown in the drawings. The collar G is provided with an annular groove g to receive the upper end of the spring, which end passes through a slot or opening d in the collar D and has on its upper surface a lug or extension g, formed with openings 9 to receive a pin 9 when it is desired to secure the collars D and G together. The lower portion of the collar G is provided with a lug g to engage the lug b on the upper portion of the spindle, and near the lug g is a recess 9 to receive the upper part of the lug b to prevent the collar G turning with the collar D when the tension of the spring is being regulated thereby. After the tension of the spring has been suitably regulated the pin 9 which has its inner end tapered, may be inserted through one of the openings cl in the collar D into one of the openings 9 in the collar G, when the lastnained collar will be raised out of engagement with the lug and allowed to turn with the collar D, the beveled or tapered end of the pin 9 causing said upward movement of the collar G, which is located within the tensionregulating collar.

The operation of my hinge is simple, as follows: The portion 1) of the spindle is inserted into the socket-piece E on the door, when by turning the door in one direction the lug b will engage the projection g on the collar G, and as it and the collar D are secured together by means of the pin 9 said collars will rotate with the spindle and carry with them the upper end of the spring 11, which, as before stated, passes through the recess (1 in the collar D and into the groove 9 of the collar G, in which operation the lower portion of the spring is firmly held by means of the collar F, whose lug f contacts with the lug a in the lower portion of the casing. \Vhen the door is swung in the opposite direction, the collar F will be turned by reason of the lug b on the spindle B engaging with the lugfon said collar and carry therewith the lower portion of the spring, whose lower end, as before stated, engages the recess f in the lower collar. To regulate the tension of the spring, a bar or rod may be inserted through the opening 0 in the cover G into one of the openings 01 in the collar D, which may be turned to the proper position, when the pin g may be inserted to secure the collars D and G together.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a casing having in its lower portion a lug and on its upper part a horizontal extension, of a cover for the upper part of the casing having a slot in its walls and a central opening, a spindle provided with projections or lugs in its upper and lower parts and having its upper end formed other than cylinder to fit in a correspondingly-shaped socket in the door and having its hearings in the casing, a collar surrounding the lower part of the spindle and provided with lugs to engage the lower lug on the spindle and the one on the casing, a grooved collar located on the upper part of the spindle and having on its lower part a lug and a recess to engage the upper lug on the spindle, and on its upper portion alug or projection provided with openings, a tensionregulating collar surrounding the last-named collar and provided with a series of openings, a pin having one of its ends tapered and adapted to be inserted in the openings of the upper collars to secure them together, and a coil-spring located in the casing and engaging the tcnsion-collar and the lower collar, substantially as described.

2. In a spring-hinge the combination with a casing, of a spindle having its bearings therein and provided with a lug on its upper portion, of a collar located on the upper part of the spindle and having on its lower part a lug, and a recess to engage the lug on the spindle, and on its upper portion a lug or projection provided with openings, atensionregulating collar surrounding the other collar and provided with a series of openings, and a pin having one of its ends tapered to raise the first-named collar out of engagement with the lug on the spindle, substanstantially as described.
